Abstract : The end of the monopoly of sociologists on social scientific network analysis has raised new questions about time and space in networks. This paper, mostly intended to be read by historians, archaeologists and political scientists, reviews existing works and circumscribes open questions as regards time, and especially historical time. It presents two currents of research that have produced cumulative results: on the one hand, the production of interpretable animated visualizations of changing networks, and on the other hand, the so-called -actor-oriented- statistical modeling of network dynamics. It also presents comparatively under-discussed questions: those that have to do with the definition, gathering and coding of data, and the drawing up of hypotheses.
